TL;DR: A Swiss cut diamond has 33 or 34 facets — more than a single cut's 17 or 18, but fewer than a modern brilliant's 57 or 58. It sits as a genuine middle ground, historically used for small and mid-size accent stones where full brilliant faceting wasn't considered worth the extra cutting effort.
Where the Swiss Cut Sits in the Faceting Story
As diamond cutting evolved from the simplified single cut toward the full modern brilliant, the Swiss cut developed as a genuine intermediate step — doubling the single cut's facet count without going all the way to the 57 or 58 facets of a full brilliant. This made it a practical compromise: noticeably more sparkle than a single cut, at less cutting time and cost than a full brilliant.
Where Swiss Cuts Were Typically Used
Like the single cut, Swiss cuts were most commonly applied to smaller accent stones — melee used in pavé work, cluster settings, and antique jewellery where dozens of small stones needed to be cut efficiently rather than each one individually maximised for brilliance. A full brilliant cut on very small stones offered diminishing returns for the extra faceting work involved, making the Swiss cut a sensible middle ground for the period.
How It Compares Visually
A Swiss cut diamond shows noticeably more life than a single cut of the same size, though still less refined sparkle than a modern brilliant — the facet pattern reads as simpler and the light return less scattered and precise. For restoring or matching antique pieces from the era when Swiss cuts were standard, this specific character matters more than raw brilliance.
